THE DRAKON OPHIOGENEIKOS was a Dragon-serpent of north-eastern Mysia who impregnated a girl named Halia when she was visiting a sacred grove of the goddess Artemis. Halia bore him a son named Ophiogenes (the Serpent Born), ancestor of the Ophiogenees tribe which inhabited the region.

According to Crates of Pergamon and Varro, there existed in the vicinity of Parium on the Hellespont a race of men called Ophiogenees (the Serpent-Born) who were able to cure poisonous serpent-bites with a mere touch of the hand.

Strabo, Geography 13. 1. 14 (trans. Jones) (Greek geographer C1st B.C. to C1st A.D.) :
"The city Parion is situated on the sea [the Hellespontos]; it has a larger harbor than Priapos . . . Here is told the mythical story that the Ophiogeneis are akin to the serpent tribe : and they say that the males of the Ophiogeneis cure snake-bitten people by continuous stroking, after the manner of enchanters, first transferring the livid color to their own bodies and then stopping both the inflammation and the pain. According to the myth, the original founder of the tribe, a certain hero, changed from a serpent (ophis) into a man."

Aelian, On Animals 12. 39 (trans. Scholfield) (Greek natural history C2nd A.D.) :
"Halia (Sea Brine), the daughter of Sybaris, was entering a grove of Artemis, the grove was in Phrygia [Mysia], when a divine Drakon appeared to her--it was of immense size--and lay with her. And from this union sprang the Ophiogeneis (Snake-born) of the first generation."
